A common light that illuminates on your dashboard is for your tire pressure. Keep in mind that there might not be a serious issue when it's illuminated as the sensors tend to be very sensitive. If at least one tire has a slight decrease in pressure after driving in Cedar Rapids, IA, then the light could come on, especially if there's a sudden change in the outdoor temperature.
Another issue that could cause the light to come on is a malfunction of the sensor itself. Someone at Cassill Motors can look at the electrical system to ensure that everything is working correctly so that you get the correct information.
If your tires have recently been rotated or changed, then the pressure might not be just where it's supposed to be, which can result in the light illuminating. Keep in mind that even if there's a minor issue, you want to check your tires to ensure that one isn't going flat.
